Plate-fin condenser for condensation of low pressure steam in the presence of noncondensable gases

PDF Version Also Available for Download.

Description

Condensation of steam in the presence of noncondensable gases was carried out in a plate-fin condenser. A three-water pass test unit was designed for the ocean-thermal energy conversion system in Hawaii. A point-wise calculation method was used for the cross-flow arrangement and the local heat- and mass-flux calculation was carried out on the basis of the Colburn-Hougen analysis. The test unit consisted of extruded water passages and finned surface on the steam side. The core unit was bonded with a thermally conductive epoxy (Loctite{reg_sign}) with welded joints along seam lines. The present investigation provides a design basis for the development ... continued below
